Granny flats are quickly becoming a popular solution for Auckland homeowners who need more usable space without moving or doing a major renovation. These self-contained units are built on the same section as a main home and offer flexibility for a wide range of living situations.
For families, a granny flat can provide a private, comfortable space for elderly parents, young adults, or long-term guests. For others, it can serve as a rental unit, a home office, or a separate area for hobbies or side businesses. The layout is compact, but the impact is big—granny flats give you more control over how you use your property.
As housing costs rise and land becomes harder to come by, granny flats offer a practical way to make better use of existing space. They’re cost-effective, add value to your home, and suit a range of property types across Auckland.

Ways To Connect With JRA Construction
What Is a Granny Flat?
Granny flats come in a few forms:
- Detached: A separate unit, often in the backyard.
- Attached: Built onto the main house but with its own entrance.
- Internal: Created by converting part of the main home, like a basement or garage.
Some people call them minor dwellings or secondary units. Whether you’re thinking about a granny flat or a house with granny flat, the idea is the same—more usable space on your existing land. In Auckland, there are specific council rules around size, placement, and access, so it’s important to plan with those in mind.
Benefits of Building a Granny Flat
- Extra space for family – Give elderly parents or adult children a place to live nearby while still maintaining privacy.
- Rental income – A granny flat can become a steady source of extra income, especially in high-demand areas.
- Adds property value – Homes with a legal second dwelling often attract more interest from buyers.
- Flexible use – A home office, a studio, a guest house—granny flats can adapt as your needs change.
- Cost-effective – Compared to building an extension or upsizing to a new home, a granny flat is usually more affordable and quicker to complete.
